He should have caught up with me inside of fifteen minutes at the outside, if he'd been able to get on the next train after mine. But then there was that station agent to be considered. And Rafe didn't have a solitary coin on him; he'd have to break one of those fifties. I now remembered something that I'd been noticing half my life and that had never meant anything to me until today - a little sign outside each subway change booth, advising the public that the agent wasn't obliged to make change for anything bigger than $1. Never get mixed up in a murder, flashed through my mind insanely, unless you've got plenty of small change. ("Don't Wait Up For Me, Tonight")
